Abstract
- Pilomatricoma is a benign skin tumor that arises from hair follicle stem cells. It typically presents in the facial region and rarely involves the palms and soles. A 15-year-old boy presented with a solitary tender nodule on the left sole. He had a history of plantar warts on the same site and had received multiple treatments including cryotherapy and intralesional bleomycin injection for nine months. Excisional biopsy was performed, and the specimen showed a well-demarcated mass in the deep dermis with basaloid cells undergoing abrupt keratinization. Ghost cells were seen with calcification. Based on these findings, he was diagnosed with pilomatricoma on the sole. We report a case of pilomatricoma, which developed on a site without hair follicles.
